If a piece of DNA breaks off a chromosome and attaches itself to a nonhomologous chromosome at another location what type of change has occured?
If a piece of DNA breaks off a chromosome and attaches itself to a nonhomologous chromosome at another location translocation is the type of change that has occurred. The chromosomal pieces are moved to a new location.
A chromosome that is exposed to a mutagen breaks into two pieces. A portion off one of the ends is removed before the two pieces rejoin. The mutation that occurs is?
The mutation that occurs is known as a deletion. When a chromosome breaks and a portion is removed before the fragments rejoin, it results in the loss of genetic material from that chromosome. This deletion can lead to disrupted gene function and may have various effects on the organism, depending on the genes affected and the size of the deleted segment.
What is the name of the 46 pieces human DNA break into?
Chromosome
What does the chromosome number say about the organism?
It tells you how many separate pieces of chromatin is found in its genome.
Do bacteria cell have single or multiple chromosomes of dna?
Bacteria cells typically have a single chromosome of DNA, which is circular in shape. This DNA molecule contains all the genetic information necessary for the bacterium to survive and reproduce. Some bacteria may also have plasmids, which are smaller, extra-chromosomal pieces of DNA that carry additional genetic information.
On a packet-switched network What files and email messages are broken down into small pieces called?
iIt is called a frame
Pieces of DNA stored in yeast cells are called?
The circular DNA molecules that can be found in bacteria are called plasmids. Plasmids are a separate DNA molecule that can replicate independently of chromosomal DNA. Plasmids are commonly used in Biology classes to teach students about splicing.
What does spontaneous gene mutation mean?
Genes are a few pieces along a chromosome. When a cell divides, the chromosome is copied. Some time the copy is not exact. Have you ever copied something and ever made a mistake? A gene might have an extra instruction added or an instruction deleted. Sometimes, a gene will be duplicated. Frequently the mistake causes the death of the cell. Sometimes it gives an organism an advantage of some type. Some people in parts of Russia can not catch AIDS due to a mutation. At one time such changes were called spontaneous. Now it is suspected such changes are caused by mistakes in copying.
How can genetic counselors predict genetic disorders?
Well certain disorders are found on certain chromosomes and on certain parts of the chromosome. How they find out how, i don't know. But if some pieces of a specific chromosome they can predict they will have a certain disorder

What type of disorders are karyotyping used to diagnose?
Chromosomal disorders can be observed in a human karyotype. It can show whether there are extra chromosomes, or missing chromosomes, or malformed chromosomes, or whether chromosomes have extra pieces, or missing pieces.
Circular DNA molecule that is not part of the chromosome in bacterial cells?
The circular DNA molecule that is not part of the bacterial chromosome is called a plasmid. Plasmids are small, extrachromosomal pieces of DNA that can replicate independently of the bacterial chromosome. They often carry genes that provide bacteria with additional functions, such as antibiotic resistance.
